A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.

The bearing surfaces of manhole frames and covers are machined to assure flatness and prevent them from becoming dislodged by traffic.

We manufacture and supply reinforced concrete manhole cover slabs with a wide range of openings to suit our manhole ring. Designed to a heavy duty specification our slabs form a secure cover for the manhole chamber below.


Extend your manhole by that extra few feet using our precast manhole risers. Designed to be safe, secure, and built to last – these man hole risers are perfect for any job.

Manhole Risers are used to maneuver the concrete cover to the required level. They fit between the cover slab and concrete cover allowing them to be stacked on top of each other, this eliminates the need to lay engineering brick.


Precast concrete base modules are vertical elements that are made up of a base, with or without a shoulder, fitted with flexible gaskets to ensure a watertight connection with the pipelines and other modular parts. They may also consist of polypropylene steps integrated in the form of a stairway to allow access to and maintenance of the pipeline.
